Washington: More than 100 vaccines are on pre-clinical trial worldwide to find a cure for the coronavirus and some of them have been started to be used on humans. Meanwhile, top health experts have warned that there may not be a corona vaccine in the world. In fact, such fears have been expressed because HIV and even dengue vaccine has not been found after many years of study.

Dr. David Naboro, Special Envoy of Corona Virus at the World Health Organization (WHO) said, 'There are some viruses here which have some medicine. We cannot assume that medicine will come and even if it does, does it meet all the parameters of safety and efficiency. ' Significantly, the WHO chief has also been making terrible predictions about the coronavirus and now this fear of the expert has increased the concern of the people.

According to a CAN report, Naboro said, "The worst possible situation is that there is never a vaccine." He said that people's hopes are increasing and then coming to an end, because many solutions are already being thwarted by the last difficulties. Let us tell you that for four decades now 32 million people have died of HIV, but the world has not been able to find its vaccine.
